The only significant buy this quarter was a ~36% stake increase in Resolute Forest Products (RFP) - Francis Chou has been bullish on this name since 2010 when the company was named Abitibibowater. his average cost-basis is much higher. Chou also sold more than half of his stake in Overstock (OSTK) and about 45% of Actavis (ACT). ACT is a very long-term holding (prior to 2007 when it was Watson Pharmaceuticals) and Chou is harvesting large capital gains from this position.
